Abstract

The invention provides a model training method and device, a search method and device, electronic equipment and a storage medium, and relates to the technical field of artificial intelligence, in particular to the fields of deep learning, computer vision, intelligent search and the like. According to the specific implementation scheme, a sample picture is input into a to-be-trained first model; performing global feature extraction, local region identification and sample picture reconstruction on the sample picture in the first model to obtain a target loss function; and training the first model according to back propagation of the target loss function to obtain a trained second model. According to the invention, the searching speed is fast, and the precision is high.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence technology, and in particular, to the fields of deep learning, computer vision, and intelligent search. Background technique [0002] With the development of technology, hardware acceleration processing can be realized through artificial intelligence, which is applicable to various application scenarios. For example, artificial intelligence technology can be used in hardware design involving image processing, graphic processing, video processing, etc. to improve the performance of hardware. Processing speed and processing accuracy. [0003] For example, in the field of search, the current image search has been unable to meet people's needs. People need a model with fast search speed and high precision in search processing to meet faster and more accurate image search. For this, there is no effective solution in the related art. SUMMARY OF THE INVENTION [0004] The present discl...
